What is Homestar?
Homestar is a comprehensive, independent national rating tool, run by the not-for-profit New Zealand Green Building Council, that measures the health, warmth and efficiency of New Zealand houses.
Homestar provides a clear framework for housing sustainability and performance and aims to create homes that are healthier and more efficient than much of New Zealand’s existing housing stock.
What is a Homestar rating?
A Homestar assessment will rate a home on a scale from 6 to 10.
A Homestar 6 rating or higher provides assurance that a house will be better quality, warmer, drier, healthier and costs less to run than a typical new house built simply to the building code. A Homestar 10 rating means you’ve built a world leading home.
Most new homes built to the Building Code may only achieve a Homestar 3-4 rating, and many existing New Zealand homes may achieve a Homestar 2-3 rating. Ratings of 6 and 7 are the most attainable for a standard New Zealand house.
What are the benefits?
Requesting a Homestar Assessment as part of your house design and construction process, will ensure that the building methodology, project management and building materials selected will result in increased efficiency, reduced environmental impact and an overall reduction in the running costs of your new home. A Homestar rating will provide certify your homes quality to other parties, such as future purchasers, or Banks and mortgage brokers who may provide lending incentives on Homestar rated properties.
How do we rate it?
To rate a home’s performance and environmental impact, Homestar awards points across seven categories: energy, health and comfort, water, waste, materials, site, home management, and an optional innovation category.
Each category is broken down into credits, and points are awarded based on the level of achievement in each credit.
Your house will be assessed during the design phase, through an assessment of the full and final plans, and then again after your home is constructed. This certifies that the features in the design rating have been fully implemented into the finished build, and that your new home has achieved your desired Homestar rating.
Our Homestar Assessors have been trained and accredited by the New Zealand Green Building Council, and we can help you to achieve a Homestar rating right from the concept design phase of your new home build, through to practical completion.
